REPAIR UNIT FOR ELECTRIC LAMPS.

Appflication filed October 25, 1921. Serial a... 510,203.

To all whom it may concern:

.Be it known that I, JOHN L. ADAMS, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented new and useful Improvements in Repair Units for Electric Lamps, of which the followin is a specification.

he ob ect of this invention is to provide means whereby the filaments of an electric lamp can be easily and quickly renewed by making an opening in the lamp and after breaking off a part of the glass arbor, placing thereon a filament carrying member, the filament of which is to be attached to the leadin -in wires of the lamp.

Another object 0 the invention is to provide means whereb the leading-in wires can be easily and quickly attached to the new filament.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in whic Figure 1 is' a view of a burnt out lamp.

-Figure 2 1s a similar view showing the same provided with a new filament.

The remaining figures are detail views.

In these views 1 indicates the bulb, 2 the glass arbor which supports the filaments and 3 the leading-in wiresto which the filaments are connected.

In carrying out my invention I make an opening 4 in the bulb and break oil the arbor at about the point 5. The leadingin wires are cut ofi' and the old filament and its supports removed. The new filament support consists of a spring wire coil 6 which has one end.suitably connectedi to a glass button 7 which carries the filament supports 8. The latter are made of soft copper wire to permit their bending. These su ports are bent inwardl so as to permit t e device to be passe through opening 4 and the open end of the spring coil is placed over the end of the arbor. The wire coil must have a tight fit on the arbor so that it will remain in place. The supports are then straightened out and a concentrated filament 9 passed through the eyes in said support. The ends of the filaments are then connected with the wires 3 by means of the wires 10, each of these wires 10 having a hook 11 at one end and a coil part 12 at its other end. The coil is laced over the wire 3 and if necessary a rop of suitable cement may be applied to prevent the parts from becoming detached. The hooked end of the wire is connected with. the filament. The lamp is then exhausted and sealed in the usual way.

The wires 10 form extensions over the leading-in wires 3 and permit the filamentbeing placed in the most desirable position in the bulb. This is importantas av renewed lamp with the filament in the small part of it will soon be discolored.

Thus the lamp can be used again so that it is not necessary to buy a'new one.-

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A repair unit for incandescent lamps including an insulating member, a coupling in the form of a coil secured at one end directly to said member, filament supporting arms extending from said member, and filament extension elements provided with couplings in the form of coils.

2. A repair unit for incandescent lamps including filament extension elements having couplings at their ends, one of the couplmgs of each element being in the. form of a coil. l

3. A repair unit for incandescent lamps including a button, an elongated spring coil secured directly to and extending from one side of the button, and filament supporting arms secured to the edge of the button.

4. A repair unit for incandescent lamps comprising an insulating. member, a coupling secured at one end'to said member, arms extending from said member, a concentrated filament supported by said arms and provided with terminal loops, and fila-' ment extension elements provided with hooks engaging said loops and with lead in wire engaging couplings.

5. A repair unit for incandescent lamps includin an insulating member, a coupling in the orm of a coil secured directly to said memberfarms extending from said member, a concentrated filament supported by said arms, and extension elements con nected to the ends of said filament and provided with couplings in the form of coils.

extending from said 6. A repair unit for incandescent lamps including a button, an arbor engaging coupling connected directly to the button, arms button, a concentrated filament supported by said arms, and fila- I ment extension elements having couplings for engagement with the ends of the filament and the ends of the lead in wires.
